The General Composition of the human gut Microbiota o Bacteria constitute the bulk of the gut microbiota o Archaea account for approximately 1% of the microbes in the human intestine o Viral and fungal abundance vary greatly Viral sequences account for between 1x10-5% and 2% of total dna in stool Fungal DNA, typically less than 1%, can be as high as 10%The General Composition of the Human Gut Microbiota  Bacteria constitute the bulk of the gut microbiota  Archaea account for approximately 1% of the microbes in the human intestine  Viral and fungal abundance vary greatly  Viral sequences account for between 1x10–5% and 2% of total DNA in stool  Fungal DNA, typically less than 1%, can be as high as 10%
